A ceramic molded into a honeycomb shape (hereinafter referred to as "ceramic molded product J") is used. When such a ceramic molded product is dried, a certain amount of shrinkage occurs as it dries. For example, Natural drying 1 When so-called external heat drying such as forced drying and far-infrared radiation drying, a large difference in drying shrinkage occurs between the outer periphery and the inside, resulting in cracks and fissures on the surface of the molded product. For this reason, conventionally, when drying ceramic molded products, microwave drying (internal heat drying) has been used to reduce the difference in shrinkage between the outer periphery and the inside. This is a method of drying by irradiating the ceramic molded product inside the oven and allowing the ceramic to absorb the microwave energy. ■ The strength and density of the microwave depending on the location in the oven can be adjusted to ensure uniform drying.
Using metal stirring blades to alleviate radio wave unevenness ■ Moving (rotating) the ceramic molded product in the oven to reduce the effect of radio wave unevenness - Microwave transmission (
The irradiation direction is mechanically driven to prevent uneven radio waves. Hot air is circulated within the oven to promote the heat dissipation effect on the surface of the object to be dried (ceramic molded product). A humidifier is installed inside the oven. Adjust the progress of surface drying and prevent surface cracks ■ Control and adjust the microwave output with an inverter ■ Irradiate microwaves while reducing the pressure inside the oven,
Efforts are made to accelerate drying at low temperatures and removal of emitted steam. Note that the above items (1) to (2) are appropriately combined depending on the external shape and material of the ceramic molded product.

の乾燥方法を提供することにある。Incidentally, the larger the dielectric loss coefficient of the material to be dried, the greater the microwave absorption (heat generation) effect. For this reason, in conventional microwave drying, when drying ceramic molded products with a large dielectric loss coefficient, such as those made of 5iC (silicon carbide), the difference in microwave absorption between the outer periphery and the inside becomes large. There is a problem in that it is difficult to dry uniformly. In particular, as shown in FIG.
Even if the microwaves (reflected by the reflector plate 103 and traveling vertically downward) are uniformized and irradiated by 02, the microwaves will not reach the outer periphery (corners or each side) 101.
It is intensively absorbed by a. For this reason, as shown in FIG. 6(a), when the outer peripheral part Iota is in a suitably dry state, the inner part 101b remains in an undried state (anko-like), or conversely, as shown in FIG. 6(b) As shown in FIG. 2, when the inner portion 1101b is in a suitably dry state, the outer peripheral portion 101a may already be in an over-dry state (binder out). As described above, with conventional drying methods, it is difficult to uniformly dry the entire ceramic molded product. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a method for drying a ceramic molded article that can uniformly dry the entire ceramic molded article, even if the ceramic molded article has a large dielectric loss coefficient and a rectangular parallelepiped shape.

The ceramic molded product is characterized by covering the corners and each side with a metal cover. Further, when irradiating the microwave, it is desirable to cover the outer circumferential surface of the ceramic molded product with a water-absorbing cover.

燥によるクラックや亀裂が生しることがない。Since the corner portion and each side of the ceramic molded product are covered with a metal cover, the microwaves irradiated to each side of the corner portion are reflected. Therefore, even if the ceramic molded product has a large dielectric loss coefficient, concentrated absorption of microwaves at the corner portions and each side is alleviated. Therefore, the entire ceramic molded product is dried uniformly. Further, when the outer circumferential surface of the ceramic molded product is covered with a water-absorbing cover, steam coming out from inside the molded product during drying is retained by the cover. Therefore, even if the drying progresses until the inside of the ceramic molded article reaches a suitable dry state, no cracks or fissures will occur on the outer peripheral surface due to overdrying.
